ADJUSTING SPINDLE

RETURN SPRING

The spindle is automatically returned to its upper most position when the handle is released. It is recommended that the handle be allowed to slowly return to the top position after each hole has been drilled in the material. This spring has been properly adjusted at the factory and should not be disturbed unless absolutely necessary. To adjust the return spring, proceed as follows:

DISCONNECT MACHINE FROM POWER SOURCE.

1.Loosen nuts (B) and (E) Fig. 27. Make sure spring housing (A) stays engaged with head casting.

2.While FIRMLY HOLDING spring housing (A) Fig. 27 pull out housing and rotate it until boss (D) is engaged with the next notch on the housing. Turn the housing counterclockwise to increase or clockwise to decrease spring tension. Turn nut (E) until it contacts spring housing (A), then back nut (E) out a 1/4 turn from spring housing (A). Tighten nut (B) against nut (E), to hold the housing in place. IMPORTANT: Inside nut (E) should not contact spring housing (A) when tightened.

OPERATION

Your drill press is to be used with drill bits with a shank of 1/2" or less in diameter. The following will give the inexperienced operator a start on common drill press operations. Use scrap material for practice to get a feel of the machine before attempting regular work.

The use of accessories and attachments not recommended by Delta may result in risk of injury.

IMPORTANT: When the workpiece is long enough it should always be positioned on the table with one end against the left side of the column, as shown in Fig. 28. This prevents the workpiece from rotating with the drill bit or cutting tool, causing damage to the workpiece or personal injury to the operator. If it is not possible to support the workpiece against the column, the workpiece should always be fastened to the table using clamps or a vise.
